VAPOR OIL-BURNER.

Specification of Letters Patent.

Patented May 11, 1920.

To all whom z't may concern Be it known that we, CHARLES W. TURN- BULLand JOHN H. Fox, citizens of the United States, residing at Albert Lea,in the county of Freeborn and State of Minnesota, have invented certainnew and useful Improvements in Vapor Oil-Burners; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the saine.

The present invention relates to improvements in vapor oil burners, andhas for an object to provide an improved vapor oil burner adapted tovolatilize the fuel more efliciently and deliver the fuel to the burnerunder pressure, whereby the ignitible contents of the fuel are morethoroughly burned and a correspondingly more intense flame produced.

The invention also provides an improved valve for use in connection withthe improved vapor oil burner, and which consists in the constructions,combinations and arrangements hereinafter more fully described andclaimed.

In the accompanying drawings forming a part of this application, and inwhich similar reference symbols indicate corresponding parts in theseveral views:

Figure 1 is a plan view of an improved vapor oil burner constructed inaccordance with the present invention.

Fig. 2 is a side view of the same.

Fig. 3 is a vertical sectional view of the improved burner.

Fig. 4: is a plan view of the improved valve.

Fig. 5 is a front view of the same with the parts shown in section.

Fig. 6 is a horizontal sectional view of the same; and

Fig. 7 is a longitudinal sectional view through one of the burners.

Referring more particularly to the drawings, 1 designates a base ofsuitable construction, preferably an elongated relatively narrow barhaving a cross piece 2 at one end thereof and formed at its other endinto a wide generating pan 3.

A generating coil 4 is situated above the pan 3 and connects with avaporizing coil 5 which is supported on the base 1, and has andsubstantially parallel with the base 1. v

A T coupling 9 is connected to the other end of the vapor cylinder 8,and is adapted to receive other couplings 10 and 11 which carry the twoburners 12 and 13.

At 111 is shown the improved combination valve for controlling thepassage of the fluid.

The generating pan 3, base 1, and cross piece 2 are preferably allformed in the same casting, together' with a standard 15 which rises outof the pan 3 to support the forward end of the vapor cylinder 8.

Referring more particularly to Fig. 7, 11 represents the T abovereferred to, which is threaded at opposite ends so that the threadedrear end of the burner nozzle 13 may be screwed into one end of such T11. The opposite end of the T 11 is adapted to receive a plug 16 whichis threaded and screwed therein, the plug having a reduced end 17 alsoscrew threaded to receive a packing nut 18. A needle valve is shown at19 and passes through the plug 16, T 11, and burner nozzle 13, and isadapted to regulate the flow of the fuel through the open end of saidnozzle 13. The valve 19 has a bent end 20 by which it may be grasped andmanipulated. By moving the needle 19 back and forth the orifice 21 ofthe burner or torchlmay be kept clear.

The two torches or burners 12 and 13 are arranged to direct theirrespective flames at opposite sides of the vapor cylinder 8 and abovethe vaporizing coil 5, so that the cylinder andl coil are heated andcause the proper vaporization of the fuel before it is allowed to passout through the torches.

The inner end of the vaporizing coil 5 is provided with a screw threadedopening 22 into which a vertically disposed nipple 23 is screwed, andwhich in turn is screwed into a right angularly disposed end 24 of thevapor cylinder 8.

The opposite end of the vapor cylinder 8 is also internally screwthreaded to receive and a nipple 25 to which the T 9 connects, and astrap 26 passes about the nipple 25 and T 9 and connects to the standardl5 for the purpose of holding these parts in the elevated positionshown.

Referring more particularly to Figs. 4, 5 and 6, 27 is a threaded shankof the valve casing which is provided with an oil duct 28 and an airpassage 29. This shank 27 is adapted to be screwed into the usualpressure tank. The oil passage 28 connects with an outlet 30 and isunder the control of a valve 3l, by which the quantity of oil can beregulated. The air passage 29 also connects with the outlet 30 through atransverse passage 32, the air being under the control of a valve rihepressure gage 34 is in communication with the air passage 29 and showsthe condition of the air pressure source.

The oil duct 28 also has a normally closed outlet 35 extendingvertically downward and which is under the control of a valve 3G. rElieoutlet 35 connects to a pipe 37 of very small diameter, known as thegenerating feed wire. This generating feed wire, as shown in Figs. 2 and3, extends into the generating pan 3 and is adapted to deliver' aquantity of the oil thereto when the apparatus is in cold condition andis to be started. After the delivery of a predetermined amount of oil tothe generating pan 3, a match is applied, igniting the oil .which heatsthe generating coil 4 and vaporizes the fuel therein.

The feed wire 37 is provided with a coni'- cal end 38 adapted to it in acorrespondingly formed socket in the lower end of the outlet 35, and anut 39 surrounds the feed wire 37 and is adapted to screw into theoutlet 35.

The valve casing is also provided with an inlet 40, for air underpressure, which is governed by a valve 41.

The outlet 80 of the valve casing is connected by a pipe of smalldiameter or feed wire 42 which is joined to the outlet 3() in anysuitable manner, and at its opposite end connects with the generatingcoil 4, as shown in Fig. 6. Any suitable connection may be used for thispurpose.

The oil from the pressure tank enters directly through the duct 28 andpasses in controlled quantity into and through the outlet 30 to the feedwire 42 and generating coil 4, where it becomes heated and afterwardpasses to the vaporizing coil 5 where it is further heated andvaporized, the vapor ascending into the vapor pressure cylinder S, whereit is collected in large quantities before issuing through the burnersor torches 12 and 13.

When it is desired to clean the various coils and pipes, the valve 33may be opened wide to allow air under pressure to pass through thetransverse passage 32 and through the outlet 30 to the several coils andthrough the vapor pressure cylinder to the torches.

It is obvious that those skilled in the art may vary the details ofconstruction and arrangements of parts without departing from the spiritof our invention, and therefore we do not wish to be limited to suchfeatures except as may be required by the claims.
